First responders and incident management personnel need better training resources to prepare for future disasters. Live training exercises while valuable are often very expensive to organize and conduct. Training using modeling, simulation, and gaming technologies could help to prepare for a more diverse range of scenarios than live exercises, support individual, team, or multi-organizational training needs at lower cost. Effective, technically sound, and commercially available standards-based solutions are needed. A concept demonstration has been developed at National Institute of Standards and Technology (NIST) to facilitate the identification, development, and deployment of standards that enable the integrated use of modeling, simulation, and gaming technology for incident management training, mission planning, and operational support. As one of the simulation tools selected in the concept demonstration, AutoMod was used to model the metropolitan train system in Washington DC. The concept demonstration was also used to identify use case scenarios, integration requirements, interoperability issues, standards needs, and available solutions.
